Pic. 5.16. Reducing belt tension by turning the automatic tensioner clockwise (1) belt pulley using a 16 mm wrench
6. Install a 16mm wrench on the tab of the automatic belt pulley tensioner, turn the belt pulley tensioner clockwise and remove the belt (pic. 5.16).
Attention! The belt used to remove the pulley will be damaged. Do not use the original engine accessory drive belt (use a different belt).
Never install a damaged belt on an engine.
Pic. 5.17. Alignment of the timing mark of the camshaft pulley with the center of the toothed belt housing window: 1 – a casing of a gear belt; 2 - installation mark; 3 - window
7. Turn the crankshaft clockwise so that the piston of the 1st cylinder (flywheel side) has moved to TDC, while the alignment mark of the camshaft pulley must be aligned with the center of the toothed belt housing window (pic. 5.17).
8. Holding the pulley from turning with a special tool, unscrew the bolts and remove the crankshaft pulley.
9. Remove pins 5 (see fig. 5.15).
10. Turn out bolts and remove a casing 12 a gear belt.
Pic. 5.18. Nut location (1) fastening the pulley of the toothed belt tensioner
11. Loosen the nut securing the pulley of the toothed belt tensioner, loosen the belt tension and remove it (pic. 5.18).
Attention! At installation it is necessary to use only a new gear belt.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
Pic. 5.19. The position of the toothed belt on the engine crankshaft pulley: 1 - groove of the crankshaft; 2 - installation mark; 3 - ribs
1. Turning the crankshaft clockwise, align the groove of the crankshaft with the center of the two ribs of the crankshaft casing. Also check that the crankshaft pulley alignment mark is offset one tooth to the left of the perpendicular position of the engine crankshaft (pic. 5.19).
2. Check that the timing mark on the camshaft pulley is aligned with the center of the timing belt housing window.
Pic. 5.20. Alignment of marks with pointers on the crankshaft and camshaft pulley
3. Install the timing belt so that the lines on the belt align with the marks on the crankshaft and camshaft pulley (pic. 5.20).
Pic. 5.21. Fastening the crankshaft pulley with washer No. 4 of the special tool MB996048: 1 - special tool MB996048; 2 – a bolt of fastening of a pulley of a cranked shaft
4. Install washer #4 of special tool MB996048 and bolt the crankshaft pulley to the crankshaft (pic. 5.21).
Pic. 5.22. Toothed belt tension: 1, 2 - special tool MB996048; 3 - tension torque 11 Nm
5. Install cover No. 1 of the special tool MB996048 on the crankshaft pulley mounting bolt and tighten the timing belt with a torque wrench to 11 Nm (pic. 5.22).
6. Remove special tool MB996048 and cover #1 of special tool MB996048.
Pic. 5.23. Bolt location (1) into the pulley of the toothed belt tensioner
7. Screw the bolt into the toothed belt tensioner pulley and tighten the bolt so that the belt tension does not change (pic. 5.23).
8. Check the toothed belt tension and re-adjust if necessary.
9. Fix the crankshaft pulley from turning, as when removing, tighten the pulley mounting bolt to a torque of 20 Nm and then tighten it by an angle of 115°± 15°.
